Physicists: "We need billion-dollar detectors to find these elusive neutrinos."
Neutrinos: *literally pass through entire planets without interacting*
That kitten sitting on a scale reading zero is the perfect metaphor for neutrino detection. These subatomic ghosts are so non-interactive they'll zip through a light-year of lead without stopping. Meanwhile, we're spending decades building massive underground tanks filled with cleaning fluid just to catch a handful. Classic particle physics relationship status: "It's complicated."
